SPECIFICATION forming part of Letters Patent'No. 244,699, dated' July 19, 188i. y Applicatipnledtanuarv, 1881. (No model.)

To all whom it may concern:

Be it known that I, EDMUND R. WARE, of Worcester, in the county of ,Worcester and State of Massachusetts, have invented certain new and useful VImprovements in a Means for VMounting and Supporting Solid Emery or Grinding Wheels; and I declare the following to be a description vof my said invention sufti- A furnish means for supportingand holding the `wheel in such a way that in case ot' fract'ure the pieces of the wheel are prevented from iiyin g from the arbor, thus permitting of the wheels being run at a veryvhigh "elocity with ha degree of safety not attainable by the ordinary methods ot' mounting wheels, also, to aord facilities foradapting the supporting devices-to the size of the grinding-wheel as it becomes worn away by use. I attain these objects by the means illustrated in the accompanying drawings, and herein, described, the particular subject-matter-claimed being hereinafter definitely specied.

In the drawings, Figure l is a vertical sectional view of an emery-wheel-mounted in ac-v cordance with my invention. Fig. 2 is a side view, one half showing the grinding-wheel and the other half the face of one oi' the supporting-disks. Fig. 3 is a diagram showing the ditferent sizes of supportingdisks. Fig. 4 shows one half-face view of the larger disk.` Fig. 5 shows one half-face View of the smaller disk, and Fig. 6 is an enlarged sectional viewV of one of the bearing-studs.

The letter vA denotes the arbor, on which is the back-collar A', the clamping-nut A2, and

' bindin g-washer A3, arranged for coniining the parts in the manner indicated.

B denotes the emery-wheel, which may be any ordinary solid grinding-wheel, although I prefer to have the wheel specially constructed vwith a large central eye, B', andfwith slightly greater thickness near the center than at the periphery, as the enlargement of the eye saves stock in the formation ofL the wheelsV without reducing the available working parts, and the inclination of the sides, by reason of greater thickness near the eye, gives a better hold for the supporting parts.

v G indicates the supporting-disks, one of which is arranged at each side ofthe wheelB. These disks are made with an outer shoulder, c,to it the collar A' and washer VA3, and with an inward-projecting ring or flange, C', to tit into the eye of the wheel B and retain it cen-- trally true with the arbor, while the bearingfaces of the disks are provided with numerous small studs or pins, D, of rubber, wood, paper, or other elastic or semi-elastic material, let into recesses or depressions G2 formed in the metal of the disk, which studsor pins D take the strain or bearingon the sides of the wheel B when the parts are set together, and firmly hold the wheel at numerous and distinct positions, and without permitting the metal ot' the disks to come into Contact with the material pf the wheel, thus, while securely supporting the wheel, avoiding any liability of warping or straining it by undue pressure at any part, and at the same time giving an elastic support againstI the shock and jar of use. The studs D retain their elasticity independent of each other, and each holds iirmly to the portion of the wheel againstwhich it rests,'and in the larger-sized disks the studs are arranged so that any radial line across the face of the disk will intersect one or more of the studs; hence there can be no fracture of the,wheel from the center outward, except some of the studs have a hold on the pieces at both sides of the line ot' fracture, and thus retain the parts in place after the wheel -is broken.

The disks C, I provide in a series of three,

each made with l similar shoulder c and ring-` These disks are severally provided lian ge C'.

with studs D, Vas shown in Figs. 4E, 2, and 5, andare respectively interchan ged as the wheel is worn away at the periphery.

lt' desired, the wheels B may be provided withthe bearing studs or p1ugs,an example of which is illustrated at D', the depressions IOO for their reception being formed in the sides of the Wheel when originally molded. This method is not, however, desirable, except, perhaps, for positions neartheeye or in the smaller sizes of wheels.

The recesses in which the elastic studs or plugs D are set may be dovetailed or undercut, or somewhat larger than the studs, (sec Fig. 6,) so as to allow for the expansion or swell of the studs by the pressure on their ends; and said studs may be secured in position in any suitable manner, as convenient.

What l claim as of my invention, and desire to secure by Letters Patent, is-

l. In combination with the grinding-wheel, a pair of clamping disks or plates provided with numerous independent projecting bearing-studs formed of elastic or semi-elastic material, which embrace the sides of the Wheel near the periphery thereof, substantially as and for the purpose set forth.

2. The combination, with the wheel-supporting plates C, having recesses or depressions C2, of the independent elastic plugs or studs D, arranged substantially as and for the purposes set forth.

3. rlhe combination, with the arbor A and grinding-wheel B, of the pair of interchangeable disks or plates C, provided with centering ring or langes C', and elasticbearing-studs D, for supporting the sides of said wheel, substantially as set forth.
